It's a module to convert filename wildcards from "*/*/*.txt" to a list of filenames that it matches. Just like glob() in Perl5, Dir[] in Ruby, and the "import" module in Python. I don't know of one in Perl6 that's standard. Or is there one I don't know about?

I know the people maintain Rakudo Star probably get lots of requests to make a module standard, but I think IO::Glob deserves to be part of every Perl 6 distribution. Otherwise, Perl 6 lacks a very useful feature, present in just about every other scripting language (including Perl 5).
